reset: pass real rev name to add--interactive
The add--interactive --patch mode adjusts the UI based on
whether we are pulling changes from HEAD or elsewhere (in
the former case it asks to unstage the reverse hunk, rather
than apply the forward hunk).
Commit 166ec2e taught reset to work on an unborn branch, but
in doing so, switched to always providing add--interactive
with the sha1 rather than the symbolic name. This meant we
always used the "apply" interface, even for "git reset -p
HEAD".
We can fix this by passing the symbolic name to
add--interactive. Since it understands unborn branches
these days, we do not even have to cover this special case
ourselves; we can simply pass HEAD.
The tests in t7105 now check that the right interface is

the buffer prepared by its only caller in builtin/checkout-index.c.

checkout: proper error message on 'git checkout foo bar --'
The previous code was detecting the presence of "--" by looking only at
argument 1. As a result, "git checkout foo bar --" was interpreted as an
ambiguous file/revision list, and errored out with:
error: pathspec 'foo' did not match any file(s) known to git.
error: pathspec 'bar' did not match any file(s) known to git.
error: pathspec '--' did not match any file(s) known to git.
This patch fixes it by walking through the argument list to find the
"--", and now complains about the number of references given.

checkout: allow dwim for branch creation for "git checkout $branch --"
The "--" notation disambiguates files and branches, but as a side-effect
of the previous implementation, also disabled the branch auto-creation
when $branch does not exist.
A possible scenario is then:
git checkout $branch
=> fails if $branch is both a ref and a file, and suggests --
git checkout $branch --
=> refuses to create the $branch
This patch allows the second form to create $branch, and since the -- is
provided, it does not look for file named $branch.

graph: fix coloring around octopus merges
When drawing the graph of an octopus merge, we draw a horizontal line
from parents 3 and above into the asterisk representing the commit. The
sections of this line should be colored to match the graph lines coming
in from above.
However, if the commit is not in the left-most column we do not take
into account the columns to the left of the commit when calculating
these colors. Fix this by adding the appropriate offset to the column
index used for calculating the color.

gc: remove gc.pid file at end of execution
This file isn't really harmful, but isn't useful either, and can create
minor annoyance for the user:
* It's confusing, as the presence of a *.pid file often implies that a
process is currently running. A user running "ls .git/" and finding
this file may incorrectly guess that a "git gc" is currently running.
* Leaving this file means that a "git gc" in an already gc-ed repo is
no-longer a no-op. A user running "git gc" in a set of repositories,
and then synchronizing this set (e.g. rsync -av, unison, ...) will see
all the gc.pid files as changed, which creates useless noise.
This patch unlinks the file after the garbage collection is done, so that
gc.pid is actually present only during execution.
Future versions of Git may want to use the information left in the gc.pid
file (e.g. for policies like "don't attempt to run a gc if one has
already been ran less than X hours ago"). If so, this patch can safely be
reverted. For now, let's not bother the users.

t3600: fix broken "choking git rm" test
The test 'choking "git rm" should not let it die with cruft' is
supposed to check 'git rm's behavior when interrupted by provoking a
SIGPIPE while 'git rm' is busily deleting files from a specially
crafted index.
This test is silently broken for the following reasons:
- The test crafts a special index by feeding a large number of index
entries with null shas to 'git update-index --index-info'. It was
OK back then when this test was introduced in commit 0693f9ddad
(Make sure lockfiles are unlocked when dying on SIGPIPE,
2008-12-18), but since commit 4337b5856f (do not write null sha1s to
on-disk index, 2012-07-28) null shas are not allowed in the on-disk
index causing 'git update-index' to error out.
- The barfing 'git update-index --index-info' should fail the test,
but it remains unnoticed because of the severely broken && chain:
the test's result depends solely on whether there is a stale lock
file left behind, but after 'git update-index' errors out 'git rm'
won't be executed at all.
To fix this test feed only non-null shas to 'git update-index' and
restore the && chain (partly by adding a missing && and by using the
test_when_finished helper instead of manual cleanup).

http: use curl's tcp keepalive if available
Commit a15d069 taught git to use curl's SOCKOPTFUNCTION hook
to turn on TCP keepalives. However, modern versions of curl
have a TCP_KEEPALIVE option, which can do this for us. As an
added bonus, the curl code knows how to turn on keepalive
for a much wider variety of platforms. The only downside to
using this option is that not everybody has a new enough curl.
Let's split our keepalive options into three conditionals:
1. With curl 7.25.0 and newer, we rely on curl to do it
right.
2. With older curl that still knows SOCKOPTFUNCTION, we
use the code from a15d069.
3. Otherwise, we are out of luck, and the call is a no-op.

order to avoid unnecessary conflicts with other "real work" patches,

cumbersome tree-wide impact, while this is a tree-wide cleanup.
